Birdsong succeeds Michele Ragusa in the role of lounge singer Jackie; Ragusa played her final performance Dec. 6. Birdsong has been seen on Broadway in Martin Short: Fame Becomes Me (Theatre World Award) and Hairspray.

Directed by Plotnick with choreography by Denis Jones and music direction by Larry Pressgrove, the new musical is based on 1970’s disaster movies with a score consisting of 1970’s pop, rock and disco hit songs.

"The year is 1979," according to press notes. "All the hottest New York City A-Listers are putting on their platform shoes and polyester disco shirts and heading to the grand opening of Manhattan's first floating casino and discotheque. Little do they know that the pier built to house the huge boat was drilled into the center of a dangerous and unstable fault-line.… Earthquake, tidal wave, infernos, killer bees, rats, sharks and piranhas all threaten the guests. Who will survive? The greedy tycoon? The aging showgirl and her 11-year-old twins? The washed-up disco star? The disaster expert still mourning the loss of his wife? The nun with the gambling addiction? The older couple with a terrible secret? And will the bra-burning feminist find love with the man who's lost his dreams?"
